Chassis

A chassis is the metal frame that houses various computing components for general computing services.

By default, IBM® Spectrum Cluster Foundation Community Edition uses a default rack and chassis configuration file. To import your own configuration file and register it with the system, use the pcmrackimport command.

To export or import a rack and chassis configuration file, use the pcmrackexport or pcmrackimport command.

The pcmrackimport -f --force command updates the rack and chassis configuration by deleting the original chassis and node location. To add a rack or chassis without deleting previous configurations, you can use pcmrackimport -f command.

Modify the IBM System x chassis password

To change the chassis password on a System x server ensure that the current chassis password and the chassis password recorded in the database are the same. To verify the password, run the following command on the management node: 
tabdump mpa
If the passwords are not the same, synchronize the passwords, run the following command on the management node: 
tabedit mpa
To change the chassis password, run the following command on the management node: 
 rspconfig chassisname USERID=new-password
where chassisname is the name of the chassis specified in the rack and chassis configuration file and new-password is the new password.

For an IBM System x server, if the rspconfig command returns an error, ensure that the USERID is the only user for BMC on your compute node.
